FENCE-POST.

E-JPECIPICATION forming part of Letters Patent No. 347,956, dated August 24, 1886.

Application filed February 4,1885. Serial No. 154,947. (No model.)

To all whom it may concern:

Be it known that I, DAVID S. PANCOAST, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new Fence'Post, of which the following is a specification.

My invention relates to an improved fencepost, intended to snpersedeall kinds of fenceposts'now in use for fencing purposes where barbed or plain wire and rods of iron orwood are used, which is composed of iron, with a screw for setting and fastening the post firmly and securely in the earth, and is cast in one piece,with the exception of the wooden plugs and pin for securing the same, as hereinafter described.

The objects of my invention are, first, to overcome the great obstacle of decay in ordinary fence-posts; second, to avoid the necessity of first digging a hole in the earth in which to set the post, thereby effecting agreat saving in labor and time; third, to form asubstantial and permanent postone that will never decay from rust after being coated with a preparation that I shall use for that purpose; fourth, to furnish through the medium of the plugs a means by which the material used for fencing can be as readily and securely fastened as on the ordinary post. I attain these objects by the construction of a post as illus trated in the accompanying drawings, in which- Figure 1 is an elevation of my improved post; Fig. 2, a longitudinal section thereof; Fig. 3, a cross-section on line B B,Fig. 1; Fig. 4, a cross-section on line 00 m, Fig. 1; and Fig. 5, a detail of the plug.

Similar letters refer to similar parts throughout the different views.

D is the spiral or thread of the screw, made with the outer surface rounded off on both the upper and lower sides, the spiral orthread surrounding the cone F from cap A to the point of the screw, with a gradual taper from starting-point at cap A. The spiral also gradually narrows in width as it approaches the extreme point.

F is a cone extending from cap A to the point of the screw surrounded by the spiral or thread D, as hereinbefore described, and in connection with the spiral D forms the complete screw by which the post is-inserted and fastened securely in the earth.

The mode of operating or inserting the post is by screwing it into the earth with a wrench applied to the upper part, by which the person using it can place one hand on the top of the post, and turn the post with the other hand by means of the wrench, by walking around it, or in the same manner as turning a and may be made at any required distance apart or in an ynumber necessary for the purposes of the purchasers.

The four equal ribs or sides of the post gradually taper from the base A (see Fig. 1) to the extreme top of the post, giving symmetry to the post, and not detracting any from its strength. By the combination of these four equal ribs, as shown in Fig. 3, I attain all necessary strength and stability for the post, and reduce the weight about four-fifths,thereby lessening the cost, which is one of the most essential features to the success of my invention.

Plate or cap A forms a base for the upper part of the post, and also a cap for the screw D and cone F, and is intended to repack the earth around the screw D that may be loosened in inserting the screw D, thereby doing away with the necessity of ramming the earth around the post, and also serves as a finish for the base of the post.

The pin 6 in Fig. 1 is for the purpose of securing the plugs G G G G (see Fig. 2) in the bosses C, Fig. 1, in case of shrinkage during hot weather.
